PORTSMOUTH, NEW HAMPSHIRE.

STEAM-HEATING RADIATOR.

SPECIFICATION forming part of Letters Patent No. 348,615, datedSeptember 7, 1886.

Application filed October 14,1885.

To all whom it may concern.-

Be it known that 1, WILLIAM XVALLACE CARMAN, of Portsmouth, in thecounty of Rockingham, of the State of New Hampshire, have invented a newand useful Improvement in Steam- Heating Radiators for \VarmingBuildings or the Apartments thereof; and Ido hereby'declare the same tobe described in the following specification and represented in theaccompanying drawing, which is a vertical section of a radiatorcontaining my invention, the nature of which is defined in the claimhereinafter presented, and which inven tion is an improvement uponUnited States Patent N 0. 316,522 in the particular hereinafter setforth.

In the drawing, A denotes a hollow or chambered base having an inclinedbottom, a, leading to an educt, I), provided with a stopcock, c. Aninduct for steam to enter the base is shown at d, it being provided witha stopcock, k. Extending upward from the tap e of the base is a seriesof pipes, B, each of which at its lower end is screwed into such tap andat its upper end is closed, excepting in having in such end a hole oraperture, f, to receive the upper end of a pipe, 0. Vithin each pipe Band concentric therewith is a pipe, 0, havingadiameter somewhat lessthan that of the bore of the pipe B, but equal to that of the hole f.Each pipe 0 extends through the inclined bottom of the base A, therebeing through such bottom an aperture, m, having a diameter equal tothat of the lower part of the pipe. The pipe 0 extends a little belowthe said bottom and also a little above the top of the pipe B, and bothat top and bottom is expanded and upset, as pipes Serial No. 179,841.(No model.)

are usually upon the head of a tubular boiler of a locomotiveengine,from which it will be seen that in case of a tight joint not being madeat either end of the pipe 0 it can be made so by screwing back orunscrewing-a little the surrounding pipe B.

In the above-described radiator steam, after having entered the base,circulates between each pipe 0 and its surrounding pipe B, and byheating both causes air about the pipe B, as well as that passing upthrough the pipe 0, to be heated.

This device is an improvement over a former invention of mine containedin the patent referred to in that the upper ends, 0, of the pipes 0being turned over at 0 form such a joint that by unscrewing the pipes Bthis joint can be closed tightly when the pipes are heated, and whencooling the inner pipes, G, contracting more necessarily precludes anyopening of said joints, and thelower ends, 0',

catching under the base Athis action is bound to take place.

Having described my invention, what I.

claim is The combination of the hollow base A, the pipes B, screwed intosaid base,and the pipes G, passing through said base and the pipes B, asdescribed, the said pipes 0 having at their upper ends the turned-overends a at 0, whereby said pipes B can be adjusted on the pipes C so asto insure a steam-tight joint, as set forth.
